Abstract: A seat supported on a fixed pedestal with a mount assembly operable to permit rotational movement of the seat about an upright axis, longitudinal fore and aft movement and transverse tilt movement of the seat. The mount assembly has a base member pivotally connected to the pedestal for movement about an upright axis. A first lock pin locks the base member in a fixed forward position. When the lock pin is released the base member can rotate about a generally horizontal axis. A pair of longitudinally located track assemblies are pivotally connected to the rear portion of the base member. The forward portions of the track assemblies are held in selected elevated positions with releasable locking arms thereby changing the tilt position of the seat. The track assemblies also have movable carriages that can be locked in selected longitudinal positions to adjust the fore and aft position of the seat.

Abstract: A power operated step assembly providing an auxiliary step adjacent the doorway of a vehicle. A box frame is secured to vehicle support structure below a doorway open to the interior of the vehicle. A step unit is movably connected to the box frame with two pair of parallel links. A transverse rod mounted on the frame is secured to one link of each pair of links so that the links are rotated in response to rotation of the rod. A power unit comprising a reversible electric motor and a lead screw carrying a nut is attached to the frame and crank arms connected to the rod. A step unit having a transverse platform pivoted to the lower ends of the links is selectively moved to an out step position and an in upper storage position in response to operation of the reversible electric motor.

Abstract: A sandwich panel multi-sided structure mountable on a vehicle body, as a pick-up truck or trailer. The structure is formed from a single flat sandwich panel comprising a bendable sheet metal facing and a rigid plywood facing bonded to opposite sides of a plastic foam core. The core is a compressible expanded polystyrene foam. The panel is provided with spaced pairs of transverse grooves extended through the rigid plywood facing toward the bendable metal facing. The grooves are along the corner sections and divide the panel into a roof section and opposite side sections. The side sections have openings for receiving window structures. The structure is formed by bending the sheet metal facing and compressing the core along the corner sections to form a roof converging outwardly and downwardly from a longitudinal ridge and upright side walls. The back of the pick-up cover is closed with an end wall having a door.
